Barafu Camp — Kilimanjaro's Summit-Night Base Camp
At 4,673m on the southeastern slopes of Kibo, Barafu Camp is the launch point for the midnight summit push on the Machame, Lemosho, Umbwe, and Northern Circuit routes. It is the place climbers are most anxious about — and the place where a 95% summit success rate is, or is not, made. The full 2026 guide: altitude, the summit-night timeline, what to do when you arrive, and the five hard rules for sleeping at 4,673m.

Our summit success rate from Barafu
Four of Kilimanjaro's seven official routes use Barafu Camp as the summit-night launch point. The camp sits in the alpine desert zone — no vegetation, exposed to the southern winds, and the launch point for what most climbers describe as the most demanding 12 hours of their lives. Whether you summit or not is decided in the 4 hours between arrival and sleep.
What Barafu Camp Actually Is
Barafu means “ice” in Swahili — a fitting name for the camp at 4,673m on the southeastern slopes of Kibo, where overnight temperatures drop to -15°C and the wind comes straight off the summit glaciers. The camp is not a fixed facility; it is a designated tent site on a flat section of volcanic scree, served by every reputable operator with 4-season mountaineering tents rated to -30°C. Most operators run individual tents (one or two climbers per tent) with a shared mess tent for dinner and briefing.
The camp is in the alpine desert ecological zone, between the heather-and-moorland of the upper Machame/Lemosho trails and the glaciated summit cone of Kibo. There is no vegetation within 200 vertical metres of Barafu. The ground is loose volcanic scree — the same material that makes the summit-night climb such hard work. Daytime temperatures at this altitude can climb to 15°C in full sun, but the moment the sun drops behind Mawenzi at 4 PM, the temperature drops 10–15°C in an hour. By 9 PM, it is colder than any night you have ever spent in a tent.
The camp's function is simple: it is the last sleep before the summit push. Climbers arrive between 12 PM and 2 PM, rest in their tents for 4–5 hours, eat a high-carb dinner at 6 PM, attend a 30-minute briefing at 6:30 PM, sleep from 7 PM, and wake at 11 PM for the midnight departure. That 4-hour sleep block is the only rest you will get before the 12–16 hour summit round-trip. The pre-summit protocol at Barafu is what separates a 60% summit rate from a 95% one.
Barafu Camp at a Glance
The reference numbers for the camp — altitude, position, climate, and what to expect on arrival. The climb profile from Barafu to Uhuru Peak is the same regardless of which route you arrive from: 1,222 vertical metres of switchbacking scree, 5–7 hours to Stella Point at sunrise.
| Attribute | Value |
|---|---|
| Altitude | 4,673 metres (15,331 ft) — the standard summit-night launch camp on Machame, Lemosho, Umbwe, and Northern Circuit |
| Etymology | Barafu means "ice" in Swahili — the camp is named for the year-round cold and the proximity to the Kibo glaciers |
| Position | Southeastern slopes of Kibo, alpine desert zone — no vegetation, no shelter from wind, full exposure to summit weather |
| Routes that use Barafu | Machame (Day 5), Lemosho (Day 6 or 7), Umbwe (Day 4), Northern Circuit (joins at the Barafu junction on summit day) |
| Accommodation | Tented camp only — 4-season mountaineering tents rated to -30°C, individual tents per climber (or shared per couple), shared mess tent for dinner and briefing |
| Sleeping altitude gain that night | Sleep at 4,673m, then climb 1,222m to Uhuru Peak (5,895m) — the largest single elevation gain of any summit-day on the mountain |
| Sleep before summit push | 4–5 hours max. Wake at 11 PM for the midnight departure. Most climbers sleep 2–3 hours in the first block, lighter sleep the second block. |
| Daytime temperature | 0°C to 15°C in full sun, with strong UV radiation. The temperature drops 10–15°C within an hour of sunset. |
| Overnight temperature | -5°C to -15°C in dry season (June–October, January–February). -20°C wind chill on the summit ridge above 5,000m. |
| Expected SpO₂ at rest | 75–82% at rest. Below 70% at high camp is a no-summit signal — your guide will have a serious conversation with you. |
| Wi-Fi / phone signal | No Wi-Fi. No phone signal. This is the last connected camp on the mountain — the summit is its own world. |
| Toilets | Pit latrines shared across the camp. Bring your own toilet paper and hand sanitiser. Expect queues at 11 PM and 5 AM. |
Which Routes Use Barafu Camp
Four of Kilimanjaro's seven official routes converge on Barafu Camp for the summit push. The two routes that do not use Barafu — Marangu and Rongai — use Kibo Hut at 4,700m instead. Marangu and Rongai climbers can read this page as background, but the specific summit-night protocols differ slightly because Kibo Hut is a dormitory, not a tent camp.
Machame Route
7 days (or 6-day Machame)
Barafu arrival: Day 5 — arrive from Karanga Camp (4,035m), summit on Day 6
Whiskey Route — the classic 7-day climb. Lava Tower acclimatisation on Day 3, Barafu summit on Day 6.
Lemosho Route
8 days (or 7-day Lemosho)
Barafu arrival: Day 6 — arrive from Karanga Camp (4,035m), summit on Day 7 (or Day 8 on the 8-day Lemosho)
The highest-summit-success route on the mountain. Two days on the Shira Plateau, full traverse to Barafu, summit on Day 7.
Umbwe Route
6 days
Barafu arrival: Day 4 — arrive from Karanga Camp (4,035m), summit on Day 5
The steepest route. Direct ascent via the Western Breach approach. Only suitable for fit, experienced climbers.
Northern Circuit
9 days
Barafu arrival: Day 8 — joins the southern routes at the Barafu junction on summit day
The longest route. Full clockwise traverse of the mountain from Londorossi Gate, then the standard summit path from Barafu.
Barafu Camp vs Kibo Hut vs Kosovo Camp
Three named summit-night launch camps on Kilimanjaro. Barafu is the tent camp on the southern routes; Kibo Hut is the dormitory hut on Marangu and Rongai; Kosovo is a smaller, higher alternative to Barafu used by some Lemosho itineraries. The trade-off between them is mainly about altitude, shelter, and route choice.
| Feature | Barafu Camp | Kibo Hut | Kosovo Camp |
|---|---|---|---|
| Altitude | 4,673m | 4,700m | 4,870m |
| Routes | Machame, Lemosho, Umbwe, Northern Circuit | Marangu, Rongai | Lemosho (alternative), some Machame |
| Accommodation | 4-season tents, individual tents per climber | Dormitory bunks, communal dining hall | Tents, smaller and quieter than Barafu |
| Vertical climb to Uhuru | 1,222m | 1,195m | 1,025m |
| Sleep altitude stress | Lower (4,673m) | Slightly higher (4,700m) | Highest of the three (4,870m) |
| Summit crowds | Busiest — 4 routes converge here | Moderate — Marangu/Rongai only | Quietest, used by smaller operators |
| Crowd-control advantage | Standard, predictable | Standard, predictable | Head start on summit morning in exchange for a tougher night |
| Shelter quality | Tent walls, private | Hut walls, communal | Tent walls, sparse |
| Best for | Standard Machame, Lemosho, Umbwe climbs | Climbers who prefer huts over tents | Operators who want to avoid Barafu crowding |
| Used for | ~85% of all Kilimanjaro summits | ~12% of all Kilimanjaro summits | ~3% of all Kilimanjaro summits |
The Summit-Night Timeline from Barafu
The full schedule from the 11 PM wake-up to the 5 PM descent-arrival at Mweka Camp. Most climbers reach Stella Point at sunrise (5:30–6:30 AM), Uhuru Peak 45 minutes later, and start the descent by 8 AM. The descent is faster than the climb — 1,200m down to Mweka Camp takes 4–5 hours on the scree.
| Time | Where | What's happening |
|---|---|---|
| 11:00 PM | Barafu Camp mess tent | Wake-up. Hot tea, light snack (biscuits, banana, bread). Full summit kit on: thermal base, fleece, down jacket, summit pants, beanie, gloves, balaclava, headlamp. Water bladder filled (1.5L minimum). Snacks in pocket (4–5 energy bars). Diamox 125mg if not taken at 4 PM. |
| 11:30 PM | Barafu Camp mess tent | Guide briefing. Pacing protocol — pole pole, 1 step per breath, rest every 100 metres. Route markers — the trail is marked by wooden posts in the scree, visible in headlamps. Decision points — turnaround at any sign of HAPE/HACE, descent is the protocol. Emergency oxygen location — guide carries 30-min cylinder; rescue protocol briefed. |
| 12:00 AM | Barafu Camp → scree trail | Departure in single file. Headlamps on, no talking. The first 90 minutes are the warm-up — switchbacks at slow pace, breathing controlled. The goal is to arrive at the steep section (around 5,000m) feeling fresh, not depleted. |
| 1:00 AM | Switchback section 4,800–5,000m | The scree gets steeper. 25–35° gradient, loose volcanic rock underfoot. The pace slows to roughly 400 vertical metres per hour. Rest every 50–100 metres — 30 seconds of standing rest, then continue. No sitting down at this altitude: standing rest keeps the blood circulating. |
| 2:00 AM | Above 5,000m, scree slopes | The hardest section. Cold deepens — typically -10°C to -15°C with wind chill. The pace slows to 250 vertical metres per hour. Most climbers feel a wave of nausea or fatigue here. This is where the slowest first hour pays off — if you paced correctly, you have reserves. Diamox headache dulls the worst of it. Rest. Breathe. Continue. |
| 3:30 AM | Hans Meyer Cave (5,150m) | Optional 5-minute stop. The cave is the only shelter on the upper mountain — a volcanic rock overhang historically used as a halfway rest point. Most climbers pass it. Above the cave, the trail crosses the saddle between Kibo and Mawenzi — wind-exposed, possibly the coldest section of the climb. |
| 5:30 AM | Stella Point (5,756m) | The crater rim. Most climbers arrive at sunrise. Photos, five minutes rest, refill water from the snow patch (boil before drinking). The final 45 minutes along the crater rim to Uhuru Peak is the flattest part of the summit ride — almost a walk, save for the altitude. The light at sunrise inside the crater is the single most memorable view on the mountain. |
| 6:30 AM | Uhuru Peak (5,895m) | Summit. The sign at 5,895m. Photographs, 10–15 minutes maximum — it is too cold to stay longer. The summit is the highest point in Africa. From here, you can see the glaciers of Kibo, the ash pit, the Furtwangler Glacier, and on a clear day, the curve of the earth on the horizon. |
| 8:00 AM | Begin descent to Barafu | The descent to Barafu is faster than the climb — 1,200m of scree down in 2–3 hours. The loose scree is your friend on the way down: step backward into the slope and let gravity do the work. Many climbers descend this section in 90 minutes. Arrive at Barafu exhausted, pack camp, eat lunch. |
| 1:00 PM | Barafu → Mweka Camp | Begin descent to Mweka Camp (3,100m). 1,573m of descent through the alpine desert, then the heather, then the rainforest. The trail is the same as the ascent, but traffic is one-way. Most climbers arrive at Mweka Camp by 5 PM, eat dinner, and sleep 10 hours straight. |
Six Things to Do When You Arrive at Barafu
The four hours between arrival at Barafu and the 7 PM sleep are the most important pre-summit window on the mountain. Most climbers waste at least one of them. The protocol below is what closes the gap between a 60% summit rate and a 95% one.
Hydrate immediately
Drink 500ml of water within 30 minutes of arrival. Your body has been climbing for 3–4 hours and is dehydrated. Continue sipping — you should aim for 1 litre between arrival and dinner. With Diamox (a mild diuretic), hydration matters more than usual.
Eat a small high-carb snack
Even if you have no appetite. A few biscuits, a banana, a slice of bread. Mount Kilimanjaro Climb serves popcorn at high camp on every climb — easy to digest, the carbs hit in 30 minutes. The point is not to feel full; it is to start the summit-night glycogen load.
Rebuild your summit bag
Headlamp + spare batteries (inside the sleeping bag, not in the pack). Summit layers: thermal base, fleece, down jacket, summit pants. Water system (1.5L minimum). Snacks (4–5 energy bars). Gloves, hat, balaclava, sunglasses, sunscreen. Everything else stays in the tent — pack only what you need.
Rest in your tent for 4–5 hours
Do not walk around the camp. The temptation to take a few photos or chat with other climbers is real, but the altitude at 4,673m means every unnecessary step costs you. Lie down. Sleep if you can. Read if you cannot. Listen to music on Aeroplane mode. The summit-night climb is 12+ hours at altitude — bank the rest now.
Eat an early dinner at 6 PM
Rice, pasta, soup, bread. Skip anything spicy or fatty. The cook will have prepared a high-carb dinner — eat it even if you have no appetite. The summit-night climb burns 4,000–6,000 calories. Whatever you eat at 6 PM, you will thank yourself for at 3 AM.
Sleep from 7 PM — wake at 11 PM
Four hours of broken sleep is the standard. Diamox 125mg at dinner reduces altitude-induced periodic breathing by 50–70% and is the most effective sleep aid at this altitude. Most climbers sleep 2–3 hours in the first block, then a lighter second block before the 11 PM wake-up. That is enough. Trust the protocol.
Five Hard Rules — What NOT to Do at Barafu
Five specific behaviours that have caused more summit failures at Barafu than any other factor. The protocol is unforgiving because the altitude is unforgiving. Each rule exists because someone, somewhere, learned it the hard way.
Do not take a hot shower
Hot showers at altitude drop your core temperature and accelerate dehydration. Operators do not offer hot showers at Barafu for this reason. If you are cold, layer up — do not warm up with water. The dehydration from a hot shower at 4,673m can manifest as a 5–10% drop in summit-day performance.
Do not take sleeping pills
Sleeping pills (zolpidem, diphenhydramine, benzodiazepines) suppress the hypoxic ventilatory response — the body's main defence against altitude. Climbers who take sleeping pills at Barafu have measurably lower SpO₂ readings overnight and a higher incidence of summit-day AMS. Diamox is the right sleep aid at altitude; it actively helps acclimatisation.
Do not smoke or drink alcohol
Both acutely reduce oxygen delivery at altitude. Smoking at 4,673m causes measurable drops in SpO₂ within 5 minutes. Alcohol rehydrates poorly, worsens periodic breathing, and impairs the breath-on-waking response that guides rely on to assess your status. If you have been a regular smoker, climb anyway — but stop at 3,000m.
Do not climb the scree around camp "to acclimatise"
Barafu is above 4,500m. Extra exertion does not improve acclimatisation; it raises your heart rate and breathing, increasing HAPE/HACE risk. The altitude physiology is already maxed out — rest is the productive behaviour at this altitude. Lie down. Stay warm. Stay horizontal.
Do not stay awake past midnight
The 4-hour sleep block is the minimum before the summit push. Your guide will wake you at 11 PM with hot tea regardless of what time you actually fell asleep. Trust the protocol. The summit night is 12+ hours — the climbers who summit at 95% are the ones who rested at 95%, not the ones who anxiously scrolled their phones through the night.
Altitude at Barafu — SpO₂, Lake Louise, and the Summit-Attempt Decision
The single most important medical decision on Kilimanjaro happens at Barafu: whether to attempt the summit at midnight, or to descend. The decision is made on three objective signals — SpO₂ at rest, the Lake Louise score, and the heel-to-toe walk test. Below is the protocol we run on every climb.
| Measurement | Green — go to summit | Yellow — discuss with guide | Red — do not summit, descend |
|---|---|---|---|
| SpO₂ at rest (after 10 minutes seated) | 75–85% | 70–75% | <70% — no summit attempt |
| SpO₂ after 2-minute walk | 70–80% | 65–70% | <65% — descent same day |
| Lake Louise AMS score (0–15) | 0–3 (no AMS or mild AMS resolving) | 4–6 (mild AMS, monitor closely) | 7+ (moderate AMS, HACE risk) — descend |
| Heel-to-toe walk test | Passes cleanly | Stumbles once, recovers | Fails — early HACE, descend immediately |
| Resting heart rate | Below 100 bpm | 100–110 bpm | >110 bpm (relative tachycardia, possible HAPE) |
| Resting respiratory rate | Below 25 breaths/min | 25–30 breaths/min | >30 breaths/min with distress (HAPE signal) |
Your guide runs these tests at 4 PM and again at 8 PM on arrival at Barafu. The decisions are made on trends, not single readings — a climber resting at 78% who walked 2 minutes and dropped to 65% is in a different risk class than a climber resting at 78% who dropped to 72%. The guide carries the medical kit and the authority on the mountain. Speak up if you feel unwell; the mountain will be there next year.
What You Pack in Your Summit Bag (and What Stays in the Tent)
The summit bag is small — about 25 litres — and contains only what you need between the 11 PM wake-up and the noon descent back at Barafu. Everything else stays in the tent. Operators provide a 4-season tent and a sleeping bag; you bring the clothing layers, hydration, snacks, and electronics.
In the summit bag
- Thermal base layer (merino or synthetic, top + bottom)
- Insulating mid-layer (fleece or light down)
- Down jacket (700–800 fill, rated to -10°C)
- Summit pants (softshell, water-resistant)
- Waterproof shell (jacket + pants, in case of summit snow)
- Beanie + balaclava (covers head, ears, neck)
- Insulated gloves + liner gloves
- Headlamp + spare batteries (in the sleeping bag pre-departure)
- Water system — 1.5L hydration bladder or two 750ml bottles
- Snacks — 4–5 energy bars, gels, or sports chews
- Sunglasses (Cat 4 UV protection — snow glare even at sub-zero)
- Sunscreen (SPF 50+, applied to face and lips at 8 PM)
- Phone (camera + emergency, in pocket with internal battery)
- Diamox 125mg (taken at 4 PM and again at 11 PM wake-up)
Stays in the tent
- Spare clothing (you wear everything on summit day)
- Toiletries (toothbrush, toothpaste, toilet paper)
- Camera gear beyond the phone (battery drain is severe in the cold)
- Books / entertainment
- Power banks (only useful in the tent — cold kills them quickly)
- Spare boots (you wear the same boots summit night)
- Day pack (only the summit bag)
- Excess water — 1.5L is enough; the scree is dry, the air is cold, you do not need more
- Food beyond the summit-night snacks — breakfast is at Barafu on the way down
All trekkers store their tents at the operator's mess tent area for the duration of the stay. Do not leave valuables in your tent between arrival and departure — the tent is not secure.
Routes That Launch from Barafu Camp
From the Blog — Summit Night & Altitude Deep Dives
Frequently Asked Questions About Barafu Camp
What is Barafu Camp on Kilimanjaro?+
Barafu Camp is the high camp at 4,673 metres (15,331 feet) on the southeastern slopes of Kibo, the summit cone of Mount Kilimanjaro. It is the launch camp for the midnight summit push on four of the seven official routes — Machame, Lemosho, Umbwe, and (as a junction point) the Northern Circuit. The name "Barafu" means "ice" in Swahili, a reference to the cold, wind-exposed conditions at this altitude. The camp sits in the alpine desert ecological zone, between the last vegetation and the glaciers of Kibo. Most climbers arrive at Barafu in the early afternoon, rest in their tents, eat an early dinner, attend a pre-summit briefing, sleep from 7 PM, and wake at 11 PM for the midnight departure.
How high is Barafu Camp in feet and metres?+
Barafu Camp sits at 4,673 metres (15,331 feet) above sea level. From Barafu to the Uhuru Peak summit (5,895m), the trail climbs 1,222 vertical metres (4,009 ft) over roughly 5–6 km of switchbacking scree. The first landmark is Stella Point at 5,756m on the crater rim — most climbers reach Stella Point at sunrise, then continue along the crater rim for 45 minutes to Uhuru Peak. The camp is in the alpine desert zone: no vegetation, daytime temperatures ranging from -5°C to 15°C, and overnight temperatures that can drop to -15°C or below with wind chill.
Which routes use Barafu Camp?+
Four of Kilimanjaro's seven official routes use Barafu Camp as the summit-night launch point: (1) Machame Route — Day 5 from Karanga Camp, summit on Day 6. (2) Lemosho Route — Day 6 from Karanga Camp, summit on Day 7 (or Day 8 on the 8-day Lemosho). (3) Umbwe Route — Day 4 from Karanga Camp, summit on Day 5. (4) Northern Circuit — joins the southern routes at the Barafu junction in the final day, summit from the same trail. The two routes that do NOT use Barafu are Marangu (uses Kibo Hut at 4,700m) and Rongai (uses Kibo Hut as the descending route on summit night).
What is the difference between Barafu Camp and Kibo Hut?+
Both are summit-night launch camps at around 4,673–4,700m, but they serve different routes and have different accommodation. Barafu is tent-only (operators provide 4-season mountaineering tents) and serves the Machame, Lemosho, Umbwe, and Northern Circuit routes. Kibo Hut is a dormitory-style hut with basic bunks and a communal dining hall, on the Marangu and Rongai routes. Kibo Hut is at roughly 4,700m — about 27 metres higher than Barafu — and is sometimes described as slightly more sheltered. Both camps are at the same physiological altitude and offer the same summit-night route. Climbers who prefer sleeping in a hut (with walls, even if simple) may prefer Marangu/Rongai; climbers who prefer tent privacy typically choose Machame, Lemosho, or Umbwe.
What should I do at Barafu Camp when I arrive?+
Six things, in this order. (1) Hydrate immediately — drink 500ml of water within 30 minutes of arrival, then continue sipping. (2) Eat a small high-carb snack even if you have no appetite. (3) Check your gear summit bag — headlamp, batteries, summit layers, water system, snacks, gloves, hat, sunglasses, sunscreen. Everything else stays in the tent. (4) Rest in your tent for 4–5 hours. Do not walk around the camp. (5) Eat an early dinner at 6 PM — rice, pasta, soup, bread. Skip anything spicy or fatty. (6) Sleep from 7 PM. Wake at 11 PM. Do not drink coffee after 4 PM. Do not take sleeping pills (they suppress breathing at altitude). Do not take a hot shower (dehydration risk). Do not smoke or drink alcohol (acute altitude risk).
What should I NOT do at Barafu Camp?+
Five hard rules. (1) Do not take a hot shower — it drops your core temperature and accelerates dehydration. (2) Do not take sleeping pills — they suppress the hypoxic ventilatory response, which is the body's main defence against altitude. Diamox is the right sleep aid; it actively helps acclimatisation. (3) Do not smoke or drink alcohol — both acutely reduce oxygen delivery at altitude. (4) Do not climb the scree slopes around camp "to acclimatise" — Barafu is above 4,500m; extra exertion buys nothing and increases HAPE/HACE risk. (5) Do not stay awake past midnight — the 4-hour sleep block is the minimum before the summit push. Your guide will wake you at 11 PM with hot tea, regardless of what time you actually fell asleep. Trust the protocol.
How do I sleep at Barafu Camp (4,673m) with altitude?+
Most climbers at 4,673m sleep poorly. The two main disruptors are altitude-induced periodic breathing (Cheyne-Stokes pattern — your breathing speeds up, then stops for 5–10 seconds, then resumes) and the cold. Three things help. (1) Diamox 125mg taken at dinner and again at 4 AM reduces periodic breathing by 50–70% (Hochstadt 2007). It is genuinely the most effective sleep aid at altitude. (2) A 4-season sleeping bag rated to -20°C, paired with a closed-cell foam mat under your inflatable mattress. The cold comes from the ground, not the air. (3) Eat your dinner, drink 500ml of warm fluid, and lie down by 7 PM. Most climbers sleep 2–3 hours in the first block, then a lighter second block before the 11 PM wake-up. That is normal. It is enough.
What is Kosovo Camp on Kilimanjaro, and how does it compare to Barafu?+
Kosovo Camp is a smaller, higher-altitude camp at approximately 4,870m, used by some Lemosho itineraries as an alternative to Barafu for the summit-night launch. It is roughly 200m higher than Barafu, which means a shorter summit-night climb (about 1,000 vertical metres to Uhuru instead of 1,222m) but more altitude stress from the higher sleep. The trade-off: a head start on summit morning in exchange for a tougher night. Kosovo is quieter than Barafu and used by operators who want to avoid the summit-night crowding at Barafu. It is not a separate route — it is an alternative final camp on the Lemosho and Machame routes, used by a minority of operators. Most climbers on the standard 7-day Machame or 8-day Lemosho summit from Barafu.
What is the summit-night timeline from Barafu?+
Standard summit-night timeline: 11:00 PM — wake-up, hot tea and a light snack, full summit kit on. 11:30 PM — guide briefing at the mess tent: pace, route, decision points, descent triggers, oxygen locations. 12:00 AM — departure in single file, headlamps across the scree. The first 90 minutes are the warm-up: switchbacks at a slow "pole pole" pace, breathing controlled, no talking. 2:00–3:00 AM — the steepest section, scree on scree, 25–35° gradient. Rest every 50–100 metres. 5:30–6:30 AM — sunrise at Stella Point (5,756m on the crater rim). Photos and a five-minute rest. 6:30–7:15 AM — the crater rim traverse to Uhuru Peak (5,895m). 7:30 AM — summit photographs at the sign. 8:00 AM — begin descent. 12:00 PM — back at Barafu, pack camp, lunch. 1:00 PM — descend to Mweka Camp (3,100m). 5:00 PM — arrival, dinner, sleep.
What is the success rate from Barafu Camp?+
Across our Machame, Lemosho, and Umbwe climbs that launch from Barafu, our summit success rate is 95% – consistent with the site's overall summit rate and verified by 149 TripAdvisor reviews at 4.8/5. The main determinants of Barafu-to-Uhuru success are: (1) route duration — Lemosho 8-day and Machame 7-day arrive at Barafu better acclimatised than Marangu 5-day. (2) Pre-Barafu SpO₂ — climbers resting at 75–82% SpO₂ at Barafu summit on average. Below 70%, the guide conversation turns serious. (3) Sleep at Barafu — any climber who slept under 90 minutes is at higher risk of bonking on the summit ridge. (4) Pacing — the slowest first hour predicts a successful summit more reliably than any other variable. The mountain rewards consistent effort over fast starts.
How cold does it get at Barafu Camp overnight?+
Overnight lows at Barafu Camp (4,673m) range from -5°C to -15°C in the dry season (June–October and January–February). With wind chill on the exposed scree slopes, summit-night temperatures can feel like -20°C to -25°C. Three layers matter: (1) a 4-season mountaineering tent rated to -30°C with a closed-cell foam mat under the inflatable mattress — the ground is colder than the air. (2) A sleeping bag rated to -20°C comfort, with a liner for an extra 5–8°C. (3) A down jacket, balaclava, and insulated boots for the summit-night start. Most operators provide summit down jackets on request; check your operator's kit list before you pack. Store electronics inside your sleeping bag at night — batteries drain fast in the cold, and a dead headlamp at Stella Point is a real safety problem.
Can I skip Barafu Camp and summit directly from Karanga Camp?+
Technically possible, not recommended. Karanga Camp sits at 4,035m — roughly 640 vertical metres below Barafu. A direct summit push from Karanga adds 9–11 km of climb and ~7 hours of additional exertion to the summit night, starting at a lower (and therefore less acclimatised) altitude. In practice, every operator we have seen use Karanga as the launch camp saw summit success rates drop to 60–70% compared to the 90%+ rate from a proper pre-summit night at Barafu. The reason is altitude physiology: a second night at 4,673m produces red blood cells that materially improve summit-day oxygenation. Two nights at Karanga instead of one at Karanga + one at Barafu does not produce the same effect. The 4-hour move from Karanga to Barafu is not optional — it is the most important vertical-metre buffer on the mountain.
